d3rlpy.metrics.scorer.dynamics_prediction_variance_scorer¶
- d3rlpy.metrics.scorer.dynamics_prediction_variance_scorer(dynamics, episodes)[source]¶
Returns prediction variance of ensemble dynamics (in negative scale).
This metrics suggests how dynamics model is confident of test sets. If the variance is large, the dynamics model has large uncertainty.
- Parameters
dynamics (d3rlpy.metrics.scorer.DynamicsProtocol) – dynamics model.
episodes (List[d3rlpy.dataset.Episode]) – list of episodes.
- Returns
negative variance.
